The 3 Different TYPES OF ROCKS (With ... - Rock Seeker

Igneous rocks are actually cooled and hardened magma. That means that Igneous rocks are formed when molten rock from deep within the earth rises to the surface (lava) and cools. Sometimes the magma will cool inside the earth before it even reaches the surface. It’s this cooling period that decides what kind of igneous rocks that magma turns into.

Pictures and Descriptions of Igneous Rock Types

03-06-2019· Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.

List of rock types - Wikipedia

The following is a list of rock types recognized by geologists. There is no agreed number of specific types of rocks. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type. Additionally, different classification systems exist for each major type of rock. There are three major types of rock: igneous rock, metamorphic rock, and sedimentary rock.

What is Obsidian? Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a "mineraloid."The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo).
